永远不会调用带有Retrofit 2.0.2的自定义xml转换器

Question

我必须使用改装2.0.2和xml api响应.但我的自定义xml转换器永远不会被调用.

玩弄这个我发现:

• 如果我使用Volley来解析相同的响应,则调用相同的自定义xml转换器;
• 如果我将GsonConverterFactory应用于我的RestClient并解析json响应,我的自定义JsonAdapter(@JsonAdapter(SomeAdapter.class))被调用.

任何人,如何让我的简单的xml转换器被调用？我做错了什么,或改装2.0.2不知何故不支持简单的xml转换器.

我解析响应的java类:

import org.simpleframework.xml.Element;
import org.simpleframework.xml.convert.Convert;

public class PassengerResponse {
  @Element
  @Convert(value = SomeConverter.class)
  private String id;
}

从未调用的自定义xml转换器:

import org.simpleframework.xml.convert.Converter;
import org.simpleframework.xml.stream.InputNode;
import org.simpleframework.xml.stream.OutputNode;

public class SomeConverter implements Converter<String> {
   @Override
   public String read(InputNode node) throws Exception {
    return null;
   }

   @Override
   public void write(OutputNode node, String value) throws Exception {
   }
}

我的改造RestClient:

import okhttp3.OkHttpClient;
import okhttp3.logging.HttpLoggingInterceptor;
import retrofit2.Retrofit;
import retrofit2.converter.simplexml.SimpleXmlConverterFactory;

public class RestClient2 {
private UserApiJSON userPassengerApi;
private static final int TIMEOUT = 120000;
private static RestClient2 INSTANCE;

public static RestClient2 getInstance() {
    if (INSTANCE == null) {
        INSTANCE = new RestClient2();
    }
    return INSTANCE;
}

private RestClient2() {

    HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
    loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

    OkHttpClient okHttpClient = new OkHttpClient();

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .addConverterFactory(SimpleXmlConverterFactory.create())
            .client(okHttpClient.newBuilder().connectTimeout(TIMEOUT, TimeUnit.MILLISECONDS)
                    .readTimeout(TIMEOUT, TimeUnit.MILLISECONDS)
                    .writeTimeout(TIMEOUT, TimeUnit.MILLISECONDS)
                    .addInterceptor(loggingInterceptor)
                    .build())
            .build();

    userPassengerApi = retrofit.create(UserApiJSON.class);
}

public UserApiJSON getUserPassengerApi() {
    return userPassengerApi;
}
}

实际上,SimpleXmlConverterFactory有不同的方法来创建它的实例.)如果您只需要使自定义的Converer工作,请执行下一步:

Strategy strategy = new AnnotationStrategy();
Serializer serializer = new Persister(strategy);

Retrofit retrofit = new Retrofit.Builder().baseUrl(BASE_URL)
    .addConverterFactory(SimpleXmlConverterFactory.create(serializer))
    .client(okHttpClient.newBuilder().connectTimeout(TIMEOUT, TimeUnit.MILLISECONDS)
    .readTimeout(TIMEOUT, TimeUnit.MILLISECONDS)
    .writeTimeout(TIMEOUT, TimeUnit.MILLISECONDS)
    .addInterceptor(loggingInterceptor).build())
    .build();
